Re-wiring cavalier

I am re-wiring an old Cavalier Pepsi machine and need advice.  There is some sort of sealed junction piece that the power supply feeds into along with supply to coils, compressor and aux. controls as well as a ground.  Since I can't see inside this sealed thing (which is broken) I'm not sure how it all hooks up.  I sure don't want to hook it up wrong.  If you have some time, I could use the help.

How about a model number for us to go on...

PS Good picture though!

It's a CS-64C

Here's a wiring diagram from the manual...
It doesn't seem to reference the refrigeration unit though...?

If you have problems viewing this because our system limits dimensions, just right-click and view image to see it slightly larger. You can print it if necessary too.

Thanks for the info.  I actually have that same diagram on the inside of the front door of the machine but it is just for the lights and stuff.  If you find anything else or can point me in the right direction, I certainly would appreciate it.  You're really nice to help us green beans out!

Hi "Pepsimom" what you're looking at is the main wiring Harnesse's molded plastic junction-block. The attached sketch
shows how the wiring is done inside the junction-block, you can replace the damaged unit with a weather proof metal single-gang type box from the electical department at your local hardware outlet, I use a heavy-duty outdoor extension cord for the power cord into the machine,(after cutting off the female end) and a single outlet for the compressors plug.
some wire-nuts,& an angle bracket for mounting it to the deck-plate, you'll also need some strain reliefs/clamps for the wires going into and out of the new box.(so wires don't get yanked-out.) it's not to hard to wire up if you're handy with wirirng, or you can buy a replacement harness for a V56 from any of the suppliers listed in this site. hope this helps...

Thank you soooo much!  I had already bought a plain junction box and was just waiting to find out what hooked up to what.  You have solved my problem.  I really appreciate all of the help I've rec'd on this site. Yall are ACES! '>

My machine has 2 cords coming from the top (cold) sections.  One looks like it comes from the fan and is the plug that goes to the compressor.  The other comes from the thermostat.  What does this last wire hook up to?

[johnieG]

do you mean the cord (with two wires) that comes from the thermostat?, the fan-motor, or the vending relay?( I assumed it was a manual-crank machine)the cord that comes from the thermostat is wired just like a wall switch & lightbulb in a house the "switch" (thermostat) turns the "light" (compressor) on & off. the cord that come from the evaporator fan (cold side) is wired in Parallel with the incoming line cord just like the diagram above. which is for a manual-vend machine, got a picture of the bugger?

It is manual.  It has the long, thin, glass vertical door which you open and pull out the bottle you want.  I have hooked the wires coming from the thermostat back up to the black and white on the main power supply.  The 2 wires coming from the fan were hooked back up to a new cord to plug into the compressor.  Does that sound right?  

I wish I could just send you a photo of all of this but my desktop is in the shop.  If you need the photo, let me know and I will send that as soon as I get the big daddy back from the techs.

NO it doesn't sound right at all    STOP!!! don't plug it  in!!!
if you've wired the two wires from the Tstat across the black & white of the line cord you'll short it out when you plug it in!!!

it goes like this, Look at the wiring diagram posted above!  from the  black wire of the line cord to one side of the Tstat wire, from the other wire of the Tstat to the female outlets
brass terminal, (small slot)  the white wire connects to the the other side of the female outlets silver terminal, (large slot)

Hi
I have exactly the same setup in the pic and diagram in this thread.
I am having a weird problem though.

I have 2 wires going to my thermostat switch. When I got the machine, both wires were put on the same post of the switch (there are 2 posts).
If you place one wire on the other post, the compressor won't come on.
I figured the Tstat switch was broken and that by placing the 2 wires together on the same post, it was essentially bypassing the switch.

So, I bought a new Tstat today to get it working properly - i didn't want the compressor running continuously and burning itself out.
However, the new Tstat and switch are behaving the same as the old one.

I know it is a working Tstat - it's brand new.
What I can't figure out is why the compressor won't come on with the power going thru the Tstat. If power is fed thru one wire and goes thru the switch and its "contact" is governed by the Tstat, then when the temperature rose above say, 40, then the switch would close and send current to the compressor.

I can't for the life of me understand why it won't work.
I know that the power is traveling from one wire to the other because when I put the wires together, the compressor runs like a champ.

any ideas?
thanks!

Sounds like the thermostat is either switched off or is also faulty

I installed an aftermarket Tstat, but unfortunately, I installed one used for HEATING.

I had too much fun back in college and lost a lot of brain cells I guess.

The Tstat works perfectly if you are keeping your water heater from freezing up. That is, if the temp gets BELOW say 32 (or whatever you have it set on), the Tstat energizes and turns on whatever is hooked up to it.
I is stoopid.

thanks for the reply - gotta go get a new Tstat!
